..5 years of abstinence and thus may represent persistent functional consequences of MDMA neurotoxicity. However, alternative causes such as pre-existing group differences cannot be completely ruled out in spite of the longitudinal design...

..An outpatient program of medication-free family therapy for polysubstance drug-dependent adolescents and young adults is evaluated on the basis of multiple criteria. The family therapy provided is brief systemic early intervention...

Mood, cognition and serotonin transporter availability in current and former ecstasy (MDMA) users

..Chronic recreational ecstasy (MDMA) use has often been reported to be associated with psychopathology, memory impairments and serotonergic alterations. However, the findings have not been consistent...

"CAN Stop"--implementation and evaluation of a secondary group prevention for adolescent and young adult cannabis users in various contexts--study protocol

..However, these studies have often been limited by small sample size, lack of tracer selectivity, unreliable assessment of MDMA doses, insufficiently matched comparison groups, or region-of-interest analysis...

..The aim of the present study was to verify these findings in young subjects...
